    • Disclosed are an apparatus and method for converting the wavelength of an optical signal using a multi-mode Fabry-Perot laser diode. The apparatus controls polarization of an external pump optical signal to output a TE polarized pump optical signal, and controls polarization of a probe optical signal to output a TM polarized probe optical signal. The apparatus couples the TM polarized probe optical signal and TE polarized pump optical signal irrespective of the polarization of the optical signals. The apparatus finely controls the polarization of the pump optical signal and the polarization of the probe optical signal such that they conform to TE and TM modes of the Fabry-Perot laser diode, respectively. The Fabry-Perot laser diode injection-locks the TE polarized pump optical signal of the coupled signal to change the position of a TM mode absorption null (a point at which an output optical signal has the minimum intensity), to thereby convert the wavelength of the TE polarized pump optical signal to the wavelength of the TM polarized probe optical signal. Accordingly, a wide wavelength conversion band is provided, and inverting and non-inverting wavelength conversions are easily carried out.
    • 公开了一种使用多模式法布里 - 珀罗激光二极管转换光信号的波长的装置和方法。 该装置控制外部泵浦光信号的偏振以输出TE偏振泵浦光信号,并且控制探测光信号的偏振以输出TM偏振探测光信号。 该装置将TM极化探针光信号和TE偏振泵浦光信号耦合,而与光信号的偏振无关。 该装置精细地控制泵浦光信号的极化和探针光信号的极化,使得它们分别符合法布里 - 珀罗激光二极管的TE和TM模式。 法布里 - 珀罗激光二极管注入锁定耦合信号的TE偏振泵浦光信号,以改变TM模式吸收零点(输出光信号具有最小强度的点)的位置,从而将波长 将TE偏振泵的光信号转换成TM偏振光的波长的光信号。 因此,提供了宽波长转换频带,并且容易进行反相和非反相波长转换。
